ABSTRACT
Although improvements are continually made to the efficiency of the many chemical and mechanical manufacturing methods used to produce an ever-increasing number of compounds and products, unwanted by-products result from virtually all methods. Such by-products can exist in the vapor, liquid, or solid phase. Many are hydrocarbons, although some non-hydrocarbon materials also exist. Regardless, the many different by-products must be safely contained or destroyed to prevent potential environmental damage.
